CARBU RETO R.

SPECIFICATION forming part of Letters Patent No. 427,197, dated May 6, 1890.

Application filed December 26, 1889- Serial No. 335,025. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM H. SHANNON, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new anduseful Improvements in Carburetors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to gas-machines for the manufacture of gas, for purposes of illumination and heating, from gasoline; and it consists in a novel carburetor and in such other devices as will be described in the specification, and pointed out in the claims.

To more properly explain my invention, reference is had to the accompanying drawing, forming a part of this specification, in which The figure is a side elevation of my automatic gasoline-gas machine, partly in section.

Similar letters of reference indicate corresponding parts.

The carburetor C is suitably mounted on an elevated platform L and is preferably filled with dry rushes or red-wood bark as an absorbent. The gasoline is fed into the carburetor from the tank L, mounted on posts L, through a pipe G, provided at its discharging end within the carburetor with a perforated cross-pipe G. At this point the gasoline is slowly discharged through the perforation of the cross-pipe G into the carburetor C, and is taken up by the absorbent material therein contained. As fast as the gasoline is converted into vapor gas it passes into two gauze cones H, and from them into an archpipe H, connected to the center of which is a main supply-pipe Lpassin g downward through the platform L nected with a system of pipes for heating and illuminating purposes. The pipe Iwithin the carburetor is surrounded by a wicking I, held in place at top and bottom by rings.

This pipe I is suitably con,

air.

The object of this wicking is to permit such gasoline as drips to the bottom of the carburetor to be taken up and discharged at the upper end intothe absorbent material. The gauze cones H are secured to the bottom of the carburetor at the lower ends and to lips on the ends of the arch-pipe H at their upper ends. J is an overflow or safety pipe which relieves the carburetor of such surplus gasoline as the absorbent material may fail to utilize, and also permits of the gasoline being drawn off in case of accident. It will be seen that the receiving end of this pipe is a few inches above the bottom of the carburetor. A pipe K at the bottom of the carburetor is used for drawing off the residuum of the gasoline, which settles at the bottom of the carburetor. Surrounding the shell B of the carburetor is a hot-air chamber F, having an outside shell D. The purpose of this chamber is to maintain such a degree of temperature as will the most readily assist in converting the gasoline in the carburetor into gas. This chamber is supplied with hot-air from any convenient source through a pipe F, which enters the bottom of the chamber.

Surrounding the shell D is a water-chamber E. An aerometer A, cone-shaped, floats in suspension in the water contained in the waterchamber E, being connected to the sides of the water-chamber by chains A. Air is forced into the aerometer A through a pipe M from a drum of a tank M, which acts as a regulator, by an air-pump N, suitably driven by any power, preferably, as illustrated in the drawing, by a system of cords, pulleys, and weight. A pipe N connects the pump N and the drum M. lVhen there is a small amount of gas being consumed, the pressure of the air raises the aerometer A till the chains prevent its further ascension, and when more gas is being consumed, and the supply of air in consequence faster exhausted, the aerometer descends into the water, causing automatically an increased motion of the pump, which thus supplies immediately the required fresh The air is fed into the carburetor through a perforated cap B.

The aerometer A and cap 13 may be restantially as shown.

2. The combination, substantially as described, of the mounted gasoline-tank L, the connecting-pipe G, provided with the perforated discharge cross-pipe G the carburetor C B B, provided with gauze cones H and arch-pipe H and its connected gas-supplying pipe I, encompassed by the wicking I'- and having the escape-pipes J and K in the bottom, the hot-air chamber F, composed of the shells B and D and provided with the supply-pipe F, the Water-chamber E, the aerometer A, the chains A, the regulator air-drum M, connected by pipe M with the aerometer and by the pipe N with the air-pump N, and a suitable motor for such air-pump.

In testimony whereof I affix my signature in 30 presence of two witnesses.

WM. H. SHANNON.
